WS-X6408A-GBIC and VRF-Lite Support.

Hi All,

On a Cisco 7606 (3BXL) with Enchanced FlexWan Cards, we create a Local VRF (VRF Lite) in order to tranfer one connection without installing a new router.

Although we followed basic configuration of VRF-Lite and the show ip route vrf command, was showing all routes (static and connected), traffic was not forwarded!!!

We are using for the Test the following Card:

WS-X6408A-GBIC - 8 port 1000mb GBIC Enhanced QoS

Can anyone tell me if it is MPLS / VRF enabled in either switchport or no switchport mode?

Regards.

Re: WS-X6408A-GBIC and VRF-Lite Support.

Hi All,

The problem might not be specific to the WS-X6408A-GBIC. If I add a loopback Address and Assign it to the VRF, I Can successfully Ping it. Same Applies from a Gigabit Ethernet Port and a Serial Port (PA-8T1/E1). The Loopback Address is also Pingable from the Serial Interfaces. What I cannot make to work is traffic traversing Gigabit and seial Interfaces. While Route table looks ok, it does not work.... I cannot ping from Network 192.168.200.0/24 to 10.10.10.8/30

Any Ideas?

Routing Table: TEST_VRF

Codes: C - connected, S - static, R - RIP, M - mobile, B - BGP

D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area

N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2

E1 - OSPF external type 1, E2 - OSPF external type 2, E - EGP

i - IS-IS, su - IS-IS summary, L1 - IS-IS level-1, L2 - IS-IS level-2

ia - IS-IS inter area, * - candidate default, U - per-user static route

o - ODR, P - periodic downloaded static route

Gateway of last resort is not set

S 192.168.150.0/24 [1/0] via 10.10.10.10, Multilink1

C 192.168.200.0/24 is directly connected, GigabitEthernet5/2

10.0.0.0/30 is subnetted, 1 subnets

C 10.10.10.8 is directly connected, Multilink1

192.168.100.0/32 is subnetted, 1 subnets

C 192.168.100.10

Hi All.

Problem was solved. The Error was due to members of Multilink (serial E1) belonging to different Enchanced FLEXWANs!!!! This problem seems not to be specific to VRF but rather to Cisco 7600 Architecture since the same problem was seen in global routing table in a Test enviroment!!!
